## Long description

NeoTec Magnus MG-400W is a 400W ATX power supply intended to deliver stable primary power for desktop computers. It provides a combined 400 watts of output on a standard ATX form factor and includes the common connectors needed to power a motherboard, CPU, storage drives and add-on cards. The unit is designed for compact, fixed-output operation and targets office systems, multimedia PCs and entry-level gaming builds that do not require high-wattage or modular cabling.
Advantages
The NeoTec Magnus MG-400W offers a straightforward, no-frills power solution with a single +12V rail that simplifies power distribution for common consumer components. Its ATX compatibility ensures easy installation into most standard desktop cases, while the 400W combined output covers typical loads for basic and mid-range systems. The PSU uses standard connectors and adheres to conventional form-factor dimensions, enabling predictable integration and replacement in existing systems.
Suitable for
Office desktops and workstations with low to moderate power draw
Multimedia PCs used for video playback, streaming and web browsing
Entry-level gaming systems with a single mid-range graphics card or integrated graphics
Home builds and system upgrades where compact, fixed-output PSUs are acceptable
Key specifications
Total continuous power: 400 watts combined output
Output topology: single +12V rail for simplified power delivery
Form factor: ATX (standard desktop power supply dimensions and mounting)
Connectors: standard ATX motherboard connector, CPU power connector, SATA and Molex peripheral connectors, PCIe connector(s) as applicable
Cooling: internal fan for active cooling (manufacturer-specified fan size and noise characteristics not provided)
Protection features: basic electrical protections typically provided in consumer PSUs (over-voltage, short-circuit protection - refer to manufacturer's specifications for exact list)
How to use
Install the NeoTec Magnus MG-400W in a compatible ATX case following standard safety precautions: power off the system and unplug it from the mains before beginning. Secure the PSU to the case with the provided screws using the appropriate alignment for ATX mounting. Connect the 24-pin ATX main power cable to the motherboard, attach the CPU 4/8-pin power connector to the processor power socket, and connect SATA or Molex cables to drives and peripherals. If required, connect any PCIe power leads to add-in graphics cards. Route cables to maintain airflow and avoid pinching or kinking. After all connections are made, double-check that connectors are fully seated before restoring mains power and powering on the system.
Usage recommendations
Use this PSU in systems whose total component power demand remains within the 400W combined rating and where a single +12V rail is appropriate. For systems with high-end CPUs, multiple graphics cards, or heavy overclocking, select a higher-wattage or modular unit with detailed efficiency and protection ratings. Ensure adequate case ventilation and periodically check connections for dust or looseness to maintain reliable operation.
